According to ZDNet, Palo Alto Networks CEO Nikesh Arora has warned that enterprises are dangerously unprepared for security risks posed by AI agents, despite growing executive awareness. During a media briefing, Arora expressed concern that organizations lack visibility into what credentials AI agents possess and what systems they can access, creating a “Wild West” scenario in enterprise platforms. The threat is compounded by bad actors increasingly using AI agents to infiltrate systems, with Palo Alto’s research identifying 194,000 internet domains being used for smishing (SMS phishing) attacks. Arora revealed Palo Alto’s dual approach to addressing the crisis: integrating identity management capabilities from their CyberArk acquisition and launching Cortex AgentiX, which uses automation trained on 1.2 billion real-world cyber threat playbook executions. This security gap emerges as enterprises rapidly deploy AI agents that can access corporate systems and sensitive information much like human workers.

The Identity Management Breakdown
The fundamental problem enterprises face is that traditional identity and access management systems were designed for human users, not autonomous AI agents. When you have AI systems making function calls across multiple applications, accessing databases through RAG implementations, and orchestrating workflows across vendor platforms, you create a scenario where traditional PAM (Privileged Access Management) solutions become inadequate. The challenge isn’t just authentication—it’s about continuous monitoring of agent behavior across distributed systems. Unlike human employees who typically follow predictable access patterns, AI agents can simultaneously interact with dozens of systems, creating audit trails that current security tools struggle to correlate and analyze effectively.
The Threat Surface Explosion
What makes this particularly dangerous is the exponential growth in attack vectors. Each AI agent deployed represents not just one potential entry point, but potentially dozens as they interact with various systems and APIs. The smishing campaign research highlights how automated attacks are already scaling at rates human security teams can’t match. When you combine automated attack generation with AI agents that might have broad system access, you create a perfect storm where attackers can probe thousands of potential vulnerabilities simultaneously. The traditional “castle and moat” security model breaks down completely when you have automated systems operating both inside and outside your organizational boundaries.
Who Bears the Brunt?
The impact varies dramatically across organizational roles. Security operations center (SOC) analysts face overwhelming data volumes—terabytes of forensic information that human teams simply cannot process manually. C-level executives grapple with strategic risk decisions about deploying technology they don’t fully understand. Meanwhile, development teams are pressured to implement AI capabilities without adequate security frameworks. Smaller organizations without dedicated security teams face existential threats, as they lack the resources to monitor AI agent behavior effectively. The gap between well-resourced enterprises and smaller businesses will widen significantly, creating a two-tier security landscape where only the largest companies can afford comprehensive AI agent protection.
The Vendor Fragmentation Challenge
Another critical issue Arora touches on but doesn’t fully explore is the vendor interoperability problem. Most enterprises use multiple AI platforms, cloud providers, and security tools that weren’t designed to work together. When an AI agent from one vendor needs to access systems managed by another vendor, there’s no standardized way to track its activities across these boundaries. This creates security blind spots where malicious activity can go undetected because it’s split across different monitoring systems. The industry desperately needs cross-vendor standards for AI agent identity and behavior tracking, but we’re years away from meaningful standardization.
The Coming Regulatory Nightmare
Beyond the immediate security concerns, enterprises face significant compliance challenges. Regulations like GDPR, HIPAA, and emerging AI governance frameworks require organizations to maintain detailed audit trails of who accessed what data and when. But when AI agents are making autonomous decisions about data access, traditional audit mechanisms fail. How do you explain to regulators that an AI system granted itself temporary elevated privileges to access sensitive customer data? The legal and compliance implications could be staggering, potentially exposing organizations to massive fines and liability when AI agents violate data protection rules.
Realistic Outlook and Recommendations
The transition to AI agent security won’t happen overnight. Organizations should start by conducting comprehensive audits of all AI systems currently in use, mapping exactly what access each agent has and what data it can touch. Implementing strict privilege escalation controls and maintaining detailed activity logs are essential first steps. Most importantly, enterprises need to recognize that AI agent security requires a fundamental rethinking of identity management—it’s not something that can be solved by bolting on another layer to existing systems. The companies that survive this transition will be those that build security into their AI agent architectures from the ground up, rather than treating it as an afterthought.
